+ * Description:

+ *  socket.” When a socket is created with socket(2), it exists in a name space
+ *  (address family) but has no name assigned.
+ *
+ * Parameters:
+ *   sockfd   Socket descriptor from socket
+ *   my_addr  Socket local address
+ *   addrlen  Length of my_addr
+ *
+ * Returned Value:
+ *   0 on success; -1 on error with errno set appropriately

+ * Assumptions:
